Download or read book Marine Flatworms written by Leslie Newman and published by CSIRO PUBLISHING. This book was released on 2003-04-17 with total page 108 pages. Available in PDF, EPUB and Kindle. Book excerpt: Marine Flatworms provides a fascinating introduction to the intriguing world of polyclad flatworms, a group of large, free-living marine Platyhelminthes, which are found throughout the world but are most colourful in tropical waters. Although not related to molluscs, they are often mistaken for sea slugs because of their brilliant colour patterns. Written in an accessible style by two leading experts in the field, this book explores flatworms’ unusual structure, feeding habits, their curious reproductive behaviour (including ‘penis fencing’), their mimicry and toxicology. With a foreword by Professor Reinhardt Kristensen of the Copenhagen Zoological Museum, Marine Flatworms is the first comprehensive guide to polyclad families and genera. It contains more than 300 colour photographs from every part of the world.
Download or read book Marine Flatworms of the Tropical Indo Pacific written by Andrey Ryanskiy and published by Andrey Ryanskiy. This book was released on 2021-05-14 with total page 154 pages. Available in PDF, EPUB and Kindle. Book excerpt: Marine flatworms are some of the ocean's most beautiful of those creatures that can be encountered by divers, snorkelers or simply lovers of marine life under water or in the intertidal zone. They are relatively simple animals with soft flat bodies. In this book we will focus on the free-living highly diverse marine flatworms of the order Polycladida. Often confused with nudibranchs, they are falling under the completely different phylum platyhelminthes (Platyhelminthes, Greek "platy": flat; "helminth": worm.) The book covers the region from the Red Sea, East and South Africa to Hawaii, Marshall Islands and Guam. Inside the book: •Over 1300 full color photographs of 580+ species; • Particular attention was paid to color variations; • Live photo of hundreds of species have never before appeared in field guides or popular books; • Convenient pictorial guide at the beginning and index at the end of the book. • The book contains photographs of most of the recently described Indo-Pacific flatworms, some of them are represented by holotypes.
Download or read book Nudibranchs of the Coral Triangle written by Andrey Ryanskiy and published by Andrey Ryanskiy. This book was released on 2022-11-09 with total page 151 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nudibranchs of the Coral Triangle became the only guide to nudibranchs on the market with an up-to-date 2022 taxonomy after its major update (November 2022) This book is a field guide, an assistant for the identification of nudibranchs species in the region. It is designed for divers, underwater photographers. The book presents 1060+ species nudibranchs that can be found and photographed in depths and regions accessible to recreational diving. Photographs, showing color variations and age differences are included. A lot of species covered by this guide have never before appeared in field guides or popular books. Compact text blocks provide information about Common name, Latin name, family, geographic distribution, size, and the most distinctive features. An extensive photo index at the beginning of the book helps you to find the right group of nudibranchs, especially for readers who have not yet mastered their names. Nudibranchs or sea slugs occur throughout the world’s oceans and are present in many marine habitats. The greatest diversity of species is found in the Indo-Pacific tropics with a concentration of species within the Coral Triangle (CT), encompassing the waters of six Southeast Asian countries: Indonesia, Papua New Guinea, Philippines, Malaysia, Timor-Leste and Solomon Islands. This global epicenter of marine biodiversity covers only 1.6 percent of the planet’s oceanic area, but attracts an increasing number of divers and underwater photographers, including nudibranch lovers.

Download or read book Marine Biodiversity of Costa Rica Central America written by Ingo S. Wehrtmann and published by Springer Science & Business Media. This book was released on 2008-12-28 with total page 545 pages. Available in PDF, EPUB and Kindle. Book excerpt: Life began in the sea, and even today most of the deep diversity of the planet is marine. This is often forgotten, especially in tropical countries like Costa Rica, renowned for their rain forests and the multitude of life forms found therein. Thus this book focusing on marine diversity of Costa Rica is particularly welcome. How many marine species are there in Costa Rica? The authors report a total of 6,777 species, or 3. 5% of the world’s total. Yet the vast majority of marine species have yet to be formally described. Recent estimates of the numbers of species on coral reefs range from 1–9 million, so that the true number of marine species in Costa Rica is certainly far higher. In some groups the numbers are likely to be vastly higher because to date they have been so little studied. Only one species of nematode is reported, despite the fact that it has been said that nematodes are the most diverse of all marine groups. In better studied groups such as mollusks and crustaceans, reported numbers are in the thousands, but even in these groups many species remain to be described. Indeed the task of describing marine species is daunting – if there really are about 9 million marine species and Costa Rica has 3. 5% of them, then the total number would be over 300,000. Clearly, so much remains to be done that new approaches are needed. Genetic methods have en- mous promise in this regard.

Download or read book Interrelationships of the Platyhelminthes written by D T J Littlewood and published by CRC Press. This book was released on 2014-04-21 with total page 373 pages. Available in PDF, EPUB and Kindle. Book excerpt: Interrelationships of the Platyhelminthes elucidates the role of the flatworms in the animal kingdom. It brings together results from an international group of experts, spanning many disciplines, who give evidence for the phylogeny of flatworms and constituent major taxa. A combined approach, using traditional comparative techniques along with the modern techniques of molecular phylogeny, is utilized to show that the monophyly of the phylum is not fully established, and that the phylum may in fact consist of two groups: the acoels and their relatives, which are basal metazoans, and the Rhabditophora, which is a more derived group.
Download or read book Biodiversity of Intertidal Marine Flatworms Polycladida Platyhelminthes in Southeastern Australia written by Jorge Rodríguez Monter and published by . This book was released on 2021 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Abstract: Flatworms of the Order Polycladida are a group of free-living invertebrates found in a diversity of marine habitats, with over 800 species described worldwide. Marine flatworms are a conspicuous component of Australia's marine fauna yet have received little attention. Less than 30 scientific articles have been published on Australian marine flatworms since 1855, of which only nine include species from southeastern Australia. Here, the biodiversity and distribution of species belonging to the Order Polycladida inhabiting intertidal rocky beaches in southeastern Australian waters were identified and analysed. Sampling was conducted at low tide along the coasts of New South Wales and Victoria. Collected samples were serially sectioned for comparative anatomical studies, and tissue was removed from each individual for molecular sequencing and analyses. Both nuclear and mitochondrial DNA sequences were obtained and used as an additional source of evidence for the description of new species as well as providing further insight into the phylogenetic relationships between them. A total of 20 species, six of which are new (e.g., Eulatocestus australis sp. nov.), and a new genus (Parabolia gen. nov.) have been described, as well as two new records for Australia (e.g., Stylochoplana clara Kato, 1937) have been identified increasing our knowledge of this important component of the Australian marine biota. Keywords: flatworm, polyclad, taxonomy, systematics, cryptic, invertebrate, predator"--Page 4.

Download or read book Thorp and Covich s Freshwater Invertebrates written by James H. Thorp and published by Elsevier. This book was released on 2014-09-06 with total page 1149 pages. Available in PDF, EPUB and Kindle. Book excerpt: Readers familiar with the first three editions of Ecology and Classification of North American Freshwater Invertebrates (edited by J.H. Thorp and A.P. Covich) will welcome the comprehensive revision and expansion of that trusted professional reference manual and educational textbook from a single North American tome into a developing multi-volume series covering inland water invertebrates of the world. The series entitled Thorp and Covich's Freshwater Invertebrates (edited by J.H. Thorp) begins with the current Volume I: Ecology and General Biology (edited by J.H. Thorp and D.C. Rogers), which is designed as a companion volume for the remaining books in the series. Those following volumes provide taxonomic coverage for specific zoogeographic regions of the world, starting with Keys to Nearctic Fauna (Vol. II) and Keys to Palaearctic Fauna (Vol. III). Volume I maintains the ecological and general biological focus of the previous editions but now expands coverage globally in all chapters, includes more taxonomic groups (e.g., chapters on individual insect orders), and covers additional functional topics such as invasive species, economic impacts, and functional ecology. As in previous editions, the 4th edition of Ecology and Classification of North American Freshwater Invertebrates is designed for use by professionals in universities, government agencies, and private companies as well as by undergraduate and graduate students. - Global coverage of aquatic invertebrate ecology - Discussions on invertebrate ecology, phylogeny, and general biology written by international experts for each group - Separate chapters on invasive species and economic impacts and uses of invertebrates - Eight additional chapters on insect orders and a chapter on freshwater millipedes - Four new chapters on collecting and culturing techniques, ecology of invasive species, economic impacts, and ecological function of invertebrates - Overall expansion of ecology and general biology and a shift of the even more detailed taxonomic keys to other volumes in the projected 9-volume series - Identification keys to lower taxonomic levels

Download or read book The Weird and Wonderful World of Marine Worms written by Andrey Ryanskiy and published by Andrey Ryanskiy. This book was released on with total page 91 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is full of creatures that are weird and wonderful - marine worms! Some of them look like nightmares or aliens from outer space, others look like beautiful flowers. You have never seen most of them. Many are not yet known to science. The author and his friends - underwater photographers and marine biologists were lucky to find many fantastic beasts - a variety of marine worms. This required thousands of dives, especially night dives, and dozens of expeditions. The uniqueness of the book is also in the widest geographical range that it covers - from the Red Sea to Hawaii, including the world-famous centers of biological diversity, the Coral Triangle, the Great Barrier Reef, etc. Marine worms are recognized world champions in biodiversity. This book is the first photo guide to these secretive and often strange animals. The book is based on photographs taken by the author, as well as his friends - citizen scientists and professional marine biologists. It is designed for the general public, marine life lovers. The book is also of interest to scuba divers and underwater photographers interested in identifying their underwater finds. This photo guide should also assist marine biologists and students in the initial identification of collected marine worms. Many years ago, scientists included in "vermis" all animals that are longer than wide, without backbones. Many distinct groups of worms were described and recognized later. This book illustrates the most common groups of marine worms. It is they who are most likely to be met under water by marine life lovers, scuba divers, snorkelers. Segmented worms make up the Phylum Annelida. It is the most diverse group of marine worms. Therefore, it is not surprising that photos of annelids occupy a large part of this book. Within the annelids, the largest number of species are polychaetes. Polychaetes (meaning "many bristles") have many bristles on the body. In addition to polychaetes, segmented worms also include Peanut worms (Sipuncula) and Leeches (Clitellata) also featured in this book. Diversity of marine worms is not limited to annelids. The Ribbon worms (Phylum Nemertea) and Arrow worms (Phylum Chaetognatha) are also featured in this book. Together with Acoel worms and Acorn worms. These groups have significantly fewer species, but they are very important for our understanding of the evolution of marine life. Flatworms (order Polycladida) are featured in a separate book "Marine Flatworms of the Tropical Indo-Pacific." The book covers the region from the Red Sea, East and South Africa to Hawaii, Marshall Islands and Guam. Inside the book: • Over 820 full color photographs of 440+ species; • Particular attention was paid to color variations, for some species up to 10 photos were added; • Live photographs of most of the species have never before appeared in field guides or popular books; • Convenient pictorial guide at the beginning and genera index at the end of the book
